I need a group of unsupported aggregation functions such as bitwise aggregations (logical OR, AND, XOR…). Can I easily create new aggregation functions? Does any API for that exist?
P.S. In our reports such data as “Error Codes” from measuring devices are used. Most of them are bit mask-like numbers. So in reports we need aggregate all of the error codes.
Thank you for writing to us.
Currently, there is no easy way to extend the existing aggregation functions list with the custom one.
